Required methods

Provided methods

! includes several bit-fields:

  • the magic signature
  • continuity flag
  • depth
  • number of channels

the matrix dimensionality, >= 2

number of rows in the matrix; -1 when the matrix has more than 2 dimensions

number of columns in the matrix; -1 when the matrix has more than 2 dimensions

usage flags for allocator; recommend do not set directly, instead set during construct/create/getUMat

black-box container of UMat data

black-box container of UMat data

offset of the submatrix (or 0)

sets some of the matrix elements to s, according to the mask

C++ default parameters
  • mask: noArray()

allocates new matrix data unless the matrix already has specified size and type.

C++ default parameters
  • usage_flags: USAGE_DEFAULT
C++ default parameters
  • usage_flags: USAGE_DEFAULT
C++ default parameters
  • usage_flags: USAGE_DEFAULT
C++ default parameters
  • usage_flags: USAGE_DEFAULT

increases the reference counter; use with care to avoid memleaks

decreases reference counter;

deallocates the matrix data

moves/resizes the current matrix ROI inside the parent matrix.

internal use method: updates the continuity flag
